What is the difference between distempers and emulsions?

Distempers contain chalk/lime, unlike emulsions which contain polymeric resins. Lime is mixed with colouring pigments, glue, and a solvent like water or oil can be applied onto surfaces. Distempers do not produce a long-lasting effect and slowly peel off and colour fades away. Low-cost emulsions are better alternatives to distempers for household painting and offer much more value for money.
